You can prepare for a job interview by studying weeks in advance, but there's still no guarantee that you won't be asked a question you have no idea how to answer.
The trickiest — and most important — questions are designed to help employers gain a deeper understanding of details beyond what's listed on your resume.
A potential sales candidate, for example, might be asked to talk through how they'd approach a short sales cycle differently than a long sales cycle. A candidate interviewing for a managerial role might be asked how they'd handle customer objections or a team conflict.
These questions aren't always easy, and they often cause most people to stress and freeze up.
When you experience something that triggers immediate stress, the amount of information your brain is able to process (a.k.a your working memory capacity) decreases. Your working memory capacity is important for solving complex problems, such as tough interview questions.
Imagine being cool as a cucumber during the first 10 minutes of your interview. Then, you get hit by a question that causes you to experience sudden stress, thus making it more challenging to fully process the question and give a good response.
Stress makes you more vulnerable to entering panic mode, which is exactly what you want to avoid. When you start to panic, your working memory capacity decreases even more. This might be followed by a moment of awkward silence, ultimately bringing the interview to a grinding halt.
To prevent this from happening, the first step is to take a few deep breaths. Studies have found that deep breathing can prevent you from falling into a state of panic — and instead calm your nerves.
As I mentioned earlier, the worse thing you can do is to respond with silence. The most brilliant way to respond to a difficult question is to ask questions — and to continue asking until you get clarification on key aspects of the question.
This idea is similar to author Byron Katie's process of reducing stress. Katie, who is the founder of The Work, a method of inquiry for identifying and working with stressful thoughts, advocates that asking questions helps us get to the core of what's bothering us so we can relieve our anxieties and think more clearly.
There's proof that this works: In 2004, during his first interview at the tech giant, Google CEO Sundar Pichai encountered a tricky question about a product that he was unfamiliar with.
His response to the interviewer was simple: "I don't know."
Pichai, who recounted the experience at a talk in 2017 at the Indian Institute of Technology, said he went on to explain that he hadn't been able to use the product and then asked for additional information. As a result, the interviewer decided to give a demonstration of the product. As the saying goes, "Ask and you shall receive."
Remember, telling your interviewer that you don't know the answer is always better than spewing out a bunch nonsense in attempt to fill the silence. Research has shown that people with "intellectual humility" (a.k.a. the willingness to admit what you don't know) are better learners — and it's something hiring managers always take note of.
Here are a few types of questions that stump most candidates — and how you can give smart responses:
Hiring managers start off as being on your team. They want you to succeed. After all, the faster they fill a position, the more time they'll have to work on filling others. At the end of the day, they just want to know whether you're the kind of employee they want to work with.
Another thing to keep in mind: It's okay to make mistakes. You're going to answer a question less well than you could have. You're going to blank on something you should have known. But no company is looking for perfection. What it does want to know is how you're going to face adversity. Don't let the rest of the interview suffer from an earlier mistake.
Research on performance under pressure suggests that you start paying a lot of attention to your own actions when the stakes are high. But you can't have a natural conversion when you're focused too closely on every aspect of what you're doing.
By the time you get to an interview, you must have trust in your preparation. If you mess up, let it go and continue to interact normally with your interviewer. You'll have plenty of time to think about how to improve the way you answer once the interview is over.
